The actress, who has been on the Weatherfield show for four years, said that she would love to see Tina strike up a bond with feisty Kylie Platt (Paula Lane).
Speaking to BBC Newsbeat, Keegan explained: "I want Tina to be best friends with Kylie. Something like that.
"I've always hung around with boys on the street but I think Tina needs a new girl best mate."
The 24-year-old also continued to hit back at recent press reports which had questioned her future with fiancé Max George.
"I'm not available. I'm still with him," she explained. "At the end of the day, the people that matter to me all know the truth and that's all we need."
Coronation Street continues tonight at 7.30pm and 8.30pm on ITV1.
